Sets the planner's estimate of the average size of the working table of a recursive query, as a multiple of the estimated size of the initial non-recursive term of the query. This helps the planner choose the most appropriate method for joining the working table to the query's other tables. The default value is 10.0. A smaller value such as 1.0 can be helpful when the recursion has low fan-out from one step to the next, as for example in shortest-path queries. Graph analytics queries may benefit from larger-than-default values.
